Description

Technical Field

[0001] This utility model relates to the field of vertical injection molding machines, specifically a large vertical two-platen injection molding machine. Background Technology

[0002] A vertical two-platen injection molding machine is a type of injection molding machine suitable for large products with inserts. It can be used in industries such as automotive, electronics, daily necessities, toys, and tools. In a typical vertical two-platen machine, one or more vertical injection clamping cylinders are located at the bottom of the work platform. For large machines, this makes the worktable very high, inconvenient for operators. Existing vertical two-platen machines on the market have shortened the stroke of the booster cylinder, while the high-pressure cylinder remains stationary during the long-stroke mold opening and closing action. This lowers the worktable. This structure also has a mold plate on both the top and bottom sides of the booster cylinder, making it, strictly speaking, a three-platen type like a conventional injection molding machine. Another type of vertical two-platen machine has multiple clamping high-pressure cylinders installed at the bottom of the gateposts. This structure, with the booster cylinders below the mold plate, has limited space, hindering subsequent maintenance. Furthermore, the gateposts are not fixed at either end, a significant drawback for a vertical injection molding machine, and the worktable is not minimized.

[0003] Vertical injection molding clamping cylinders consist of one or more located at the bottom of the work platform. For large machines, this makes the worktable very high, which is inconvenient for operators. Clamping high-pressure cylinders consist of multiple cylinders installed at the bottom of the gateposts. This structure, with the pressure cylinders located below the mold plate, has limited space, which is not conducive to subsequent maintenance. Furthermore, the gateposts are not fixed at both ends, which is a major drawback for vertical injection molding machines. Therefore, a large vertical two-platen injection molding machine is proposed to address the above problems. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses a large vertical two-plate machine, including a vertical two-plate machine 10. The lower part of the frame of the vertical two-plate machine 10 is provided with a lower template 6. A green column 1 is inserted into the slot of the lower template 6. The lower template 6 and the green column 1 are fixed by a fixing nut 7. An upper template 5 is inserted into the column body of the green column 1. Long-stroke fast cylinders 9 are provided on the sides of the upper template 5 and the lower template 6. A pressure boosting cylinder 4 is provided on the upper part of the green column 1. A clamping nut 3 is provided on the upper end of the pressure boosting cylinder 4. A clamping cylinder 2 is provided on the side of the clamping nut 3. A ejector cylinder 8 is provided in the middle of the lower template 6. The ejector cylinder 8 is fixedly connected to the frame of the vertical two-plate machine 10.

[0025] The clamping cylinder 2 also includes a clamping cylinder fixing plate 21, the middle part of which is fixedly connected to the frame of the clamping cylinder 2, and the end of which is fixedly connected to the end of the clamping nut 3.

[0026] The clamping nut 3 includes: a clamping box guide block 31 and a clamping nut connecting rod 32. The block of the clamping box guide block 31 is rotatably connected to the rod of the clamping nut 3. One end of the clamping nut connecting rod 32 is fixedly connected to the side of the clamping nut 3, and the other end of the clamping nut connecting rod 32 is fixedly connected to the end of the clamping cylinder fixing plate 21.

[0027] The booster cylinder 4 includes: a booster cylinder spindle 41, a booster cylinder lower cover 42, a booster cylinder sleeve 43, and a booster cylinder piston 44. The booster cylinder spindle 41 is movably connected to the column of the Green Column 1. The outer wall of the booster cylinder spindle 41 is sleeved with the booster cylinder lower cover 42. The upper part of the booster cylinder lower cover 42 is fixedly connected to the lower part of the booster cylinder sleeve 43. The inner wall of the booster cylinder sleeve 43 is sleeved with the booster cylinder piston 44.

[0028] The lower template 6 is connected to four Green Columns 1.

[0029] Two sets of rapid cylinders 9 are provided on the sides of the upper template 5 and the lower template 6.

[0030] Working principle: When using the vertical two-platen press 10, during mold opening, the clamping nut 3 is opened by the clamping cylinder 2. The rapid cylinder 9 pushes the upper mold plate 5 upward, and the pressure boosting cylinder 4 is driven to move synchronously. The rapid cylinder 9 can accelerate the action speed. During mold closing, the clamping cylinder 2 controls the clamping nut 3 to open again, causing the rapid cylinder 9 to drive the upper mold plate 5 downward. After the upper mold plate 5 and lower mold plate 6 are fully engaged, the mold is closed, the clamping nut 3 closes, and the pressure boosting cylinder 4 is activated. When the hydraulic cylinder 4 is pressurized by oil intake, the annular groove of the clamping nut 3 engages with the annular groove of the Green column 1. The engagement of the two can withstand high pressure, achieving high-pressure mold locking. This prevents the upper mold plate 5 and lower mold plate 6 from becoming loose and having gaps during the mold closing process due to the pressure brought by the hydraulic cylinder 4, which could lead to accidents during the mold closing process. Four sets of fast cylinders 9 can be installed on the sides of the upper mold plate 5 and lower mold plate 6 to accommodate equipment with large tonnage.

[0031] Each Green Column 1 is equipped with a booster cylinder 4 above it, so that the four booster cylinders 4 can simultaneously increase pressure during the mold closing process of the upper mold plate 5 and the lower mold plate 6, so as to maintain pressure stability. The booster cylinder 4 is located above the upper mold plate 5, which not only facilitates subsequent maintenance, but also achieves the lowest possible worktable height.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
